RICHARD WV. BAINBRIDGE, OF NEW YORK, N. Y.

PAPER-MAKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 788,508, dated May 2,1905.

Application tiled December 27, 1904:. Serial No.. 238,460.

To (r/ZZ 'whom 'lit 'nm/y concern:

Be it known that I, RICHARD W. BAIN- BRIDGE, a citizen of the UnitedStates, residing in the borough of Brooklyn, county of Kings, city andState of New York, have invented a certain new and useful Improvement inPaper-Making Apparatus, of which the following is a specification.

The present invention applies more particularly to apparatus for' makingsheets of paper by hand; and the object is to provide a simple,portable, easily-handled mold utilizing the principle of gravitation incollecting the paper liber from the water in which the same may besuspended and distributing the same evenly upon a perfo'rate surface inorder that a sheet of uniform texture and thickness may be producedwithout involving the employment of skilled labor, upon which thehandmade-paper industry has heretofore depended.

In carrying out the invention I employ a mold which may take the form ofa rectangular box, the top whereof may be provided with a gauze coveringof suitable mesh, the

bottom whereof may, if desired, be detachable, and the sides whereof maybe provided with suitable ports for egress of the air when such mold isimmersed in water.

In operation upon immersing the mold in the water in which the fiber issuspended such water will under the iniiuence of gravity immediatelypass into the mold, displacing the air therein, which is allowed toescape through the ports referred to, the fiber being arrested upon thegauze covering until the accumulation has been sufhcient to produce asheet of requisite thickness, whereupon the mold may be lifted from theWater and the deposited fiber dried and otherwise treated in suitablemanner.

The invention is illustrated in the accompanying drawings, in which-Figure l is a central section of a mold eniploying my invention. Fig. 2is a top plan view thereof, a portion of the gauze covering being brokenaway; and Fig. 3 is an elevation on reduced scale, showing the moldimmersed in water. n

Referring to the drawings, in which similar letters denote correspondingparts, it will be seen that the mold is here shown as rectangular inform,.comprising the four sides t a' a2 fand the bottom B, which ispreferably detachable and provided with any suitable securing devicewhereby the same may be attached to said sides.

O designates the cover of wire-gauze of lsuitable mesh, and this may besecured in any desired manner in the position in which it isillustrated, detachably or permanently, as preferred.

D D designate ports or air-passages, here shown as two in number andeach comprising a pipe connected with one of the sides of the mold andcommunicating with the interior thereof through an opening in such side.

The method of operation is illustrated in Fig. 3. |The mold is intendedto be immersed, as above indicated, in the water in which the paper beris suspended, whereupon under the pressure of such water the air will beforced therefrom through the ports or openings above indicated, and asthe water passes into the interior of the mold the paper fiber will belaid upon the gauze covering C, the period of immersion being calculatedwith reference to the thickness of the paper to be produced.

Preferably the mold is of such height that a suiiicient quantity offiber will be deposited upon the gauze before the water-level will riseto the ports. After the fiber has been laid and the mold removed fromthe tank the water may be freed from the mold in any suitablernanner as,for instance, by the removal of the bottom B. l

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows:

I. In paper-making apparatus, the combination with a mold, of a closurefor the bottom thereof, a foraminated closure for the top thereof, suchas gauze, and a connection between the interior of said mold and theoutside atmosphere, substantially as set forth.

2. 1n paper-making apparatus, the combination with a mold, of a closurefor the bottom thereof, a forarninated closure for the top thereof, Suchas gauze, and a port in said mold communicating with the outsideatmosphere, substantially as set forth.

3. In paper-making apparatus, the combination with a mold, of adetachable closure for the bottom thereof, a foraminated closure vforthe top thereof, such as gauze, and a connection between the interior ofsaid mold and the outside atmosphere, substantially as set forth.

4. In paper-making apparatus, the combination with a mold, of a closurefor the bottom thereof, a foraminated closu re for the top thereof, suchas gauze, and means for withdrawing air or water passed to the interiorof said mold, substantially as set forth.

5. In paper-making apparatus, the combination with a container for waterhaving paper liber suspended therein, of arnold adapted for immersion inthe water in said container, said mold. having a Closure for the bottomthereof, and a closure for the top thereof of foraminated material suchas gauze, and means for withdrawing the contents of said mold after theimmersion thereof in said water, substantially as set forth.

This specification signed and witnessed this 19th day of December, 1904.
